具体实施方式 detailed description

现在将详细参照本发明的较佳实施例,其示例均以附图的形式予以示出。 Reference will now be made in detail to the present preferred embodiment of the invention, examples of which are in the form of the accompanying drawings shall be shown. 在可能的情况下,相同的参考数字在全部附图中都指代相同或相似的部件。 Wherever possible, the same reference numerals throughout the drawings all refer to the same or like parts generations. 为便于说明,将蓝光盘片(BD)选作根据本发明的光盘的示例。 For convenience of explanation, a Blu-ray Disc (BD) optical disc is selected as an example according to the present invention. 然而,很明显的是,本发明的概念的特征在于有盘片控制信息记录于其上的一种光盘,这种概念可以以相同的方式应用于DVD-RAM/-RW/+RW/-R/+R等。 However, it is clear that the concept of the present invention is characterized in that there is an optical disc recording disc control information thereon, this concept can be applied to DVD-RAM / -RW / + RW / -R same manner / + R and the like.

此外,尽管本发明所使用的术语可能选自目前众所周知的术语,但是在某些情况下某些术语是申请人任意选用的,所以在下面的描述中会详细解释其意义。 In addition, although the terms used in the present invention may be selected from the currently well-known terms, but in some cases, certain terms applicant is optionally used, so the following description will explain the meaning. 因此,在理解本发明时,对于申请人所选用的相应的术语,应该将其理解成申请人意图表达的意思,而非仅仅是术语本身的字面意思。 Thus, understanding the present invention, the applicant for the corresponding terms chosen, it should be understood to express the meaning intended by the applicants, not only the literal meaning of the terms themselves.

首先,在本发明的描述中“盘片控制信息”的意思是包括盘片记录重放的各种信息或盘片记录重放的信息在内的一块区域。 First, in the description of the present invention, the "disc control information" is meant to include a variety of information or the information recording and reproducing disk recording and reproducing the disk including a region. 并且,盘片控制信息是由盘片制造商为盘片的用户提供在盘片内预先记录的区域中或浮雕区域的一般性指定信息。 Further, the disc control information is disc information area designated users or the general relief region in the pre-recorded disc by a disc manufacturer is. 然而,不仅把盘片控制信息提供给预先记录的区域,而且还提供给可记录的区域。 However, not only the disc control information to the prerecorded area but also to a recordable area provided. 也可以把预先记录的或浮雕区域内的盘片信息复制到可记录的区域中。 The disc information may be copied within a prerecorded or embossed area can be recorded to the region. 而且,它们仅是示例性的。 Moreover, they are merely exemplary.

例如,在BD中,盘片控制信息是所谓的“盘片信息”,或者在DVD-RAM/-RW/+RW/-R/+R中,盘片控制信息是“物理格式信息”。 For example, in the BD, the disc control information is called "disc information", or DVD-RAM / -RW / + RW / -R / + R, the disc control information is "physical format information." 因此,很明显,本发明的技术背景可以完全相同地应用于DVD-RAM/-RW/+RW/-R/+R中的“物理格式信息”。 Thus, it is apparent that the technical background of the invention can be identically applied to DVD-RAM / -RW / + RW / -R / + "physical format information" R in. 为便于解释,以蓝光盘片(BD)的情形所对应的“盘片信息(在下文中缩写为DI)”为例。 For ease of explanation, in the case of Blu-ray Disc (BD) corresponding to the "disc information (hereinafter abbreviated as the DI)." Example.

图1和图2是根据本发明的光盘的结构图,其中可记录光盘足够充当可应用于本发明的光盘。 1 and FIG. 2 is a configuration diagram of an optical disk according to the present invention, wherein a sufficient function as an optical disc recordable optical disc applicable to the present invention. 此外,可记录光盘可以是可重复写入的光盘、一次性写入的光盘等中的任何一种。 Further, the optical disc may be a recordable rewritable optical disc, any of a write-once optical disk in.

图1是根据本发明具有一层记录层的单层盘片的结构图。 FIG 1 is a configuration diagram of a single-layer disc having one recording layer according to the present invention has.

参照图1,在光盘内圆周区域上提供导入区域作为管理区域,而在光盘的外圆周区域上提供导出区域也作为管理区域。 Referring to FIG. 1, a lead-in area on the optical disc in the peripheral area as a management area, and the lead-out area provided on an outer circumference area of ​​the disc also serves as the management area. 具体来讲,在盘片的内圆周区域中,预先记录的区域和可重复写入的区域或一次性写入的区域彼此分开。 Specifically, in the peripheral area of ​​the disc, regional and rewritable prerecorded or write-once area are separated from each other.

预先记录的区域是在制造该盘片的过程中已经将数据写入其中的一块区域(称为“浮雕区域”),因此用户或系统根本无法在预先记录的区域中执行数据写入。 Prerecorded area is in the process of manufacture of the disk data has been written in an area which (referred to as "relief region"), the user or the system can not perform writing of data in a prerecorded area. 在BD-RE/WO中,预先记录的区域是指定的PIC(永久信息和控制数据)区域。 In BD-RE / WO, the prerecorded area is specified in the PIC (permanent information and control data) area. 并且,在该PIC区域中记录作为盘片记录所需信息的上述盘片信息(在下文中称为“DI”)。 The recording disk as a disk for recording the information (referred to as "DI" hereinafter) required in the PIC area.

在数据区域中,所提供的是在其中记录了用户的真实数据的用户数据区域以及用来替代所产生的缺陷区域的备用区域ISA和OSA。 In the data area, a spare area is provided in which a defective area generated by the user is recorded real data, and a user data area used instead of ISA and OSA. 具体来讲,为像BD-WO这种一次性写入光盘提供用于记录缺陷和一般性管理信息的TDMA(暂时缺陷管理区域)。 Specifically, like the BD-WO is a write-once optical disc such TDMA provided for recording defect management information and general (temporary defect management area). 对于可重复写入的BD(BD-RE)而言,TDMA不是必需的,所以这种区域留作保留区域。 For BD (BD-RE) rewritable, TDMA is not necessary, so this area is reserved for a reserved area.

本发明旨在提供一种方法,用于有效地将作为盘片记录重放所需的盘片控制信息的盘片信息(DI)记录到预先记录的或可记录的区域中。 The present invention aims to provide a method for efficiently reproducing the disc control information required for disc information (DI) as disc recording to be pre-recorded or recorded area. 很明显,预先记录的区域中的记录方法被不同地应用于各种盘片。 Obviously, a recording method in the prerecorded area is differently applied to various disk. 对于BD-RE/WO而言,通过双相高频调制信号来记录作为预先记录的区域的PIC区域,根据特定的重放方法来重放相应的区域中的高频调制信号,并且从该重放中获取了信息。 For BD-RE / WO, the recorded high frequency modulated by bi-phase signal PIC area as the prerecorded area, respective reproduced frequency modulated signal according to a specific region of the reproducing method, and from the weight put the acquired information.

图2是具有双层记录层的双层盘片的图,其中以导入作为开始的记录层是指定的第一记录层“层0”,以导出作为结束的记录层是指定的第二记录层“层1” 。 FIG 2 is a view of a double disc having a double recording layer, wherein the recording layer begins to introduce the first recording layer is designated "layer 0" to derive the recording layer is designated as the end of the second recording layer "layer 1."

在双层盘片中,给盘片内圆周区域的导入和导出区域提供PIC区域,并且在PIC区域中记录相同内容的盘片信息(DI)。 In the double-layer disc, introduced to the circumference of the disc and the area within the lead-out area provided PIC area and the information recording disc of the same contents (DI) in the PIC area.

图3是图1或图2所示盘片中的PIC区域的结构图。 FIG 3 is a configuration diagram of a PIC area in the disc shown in FIG. 1 or FIG. 2. 如上所述,它意味着当获取了在高频调制PIC区域内的全部信息时,可以像图3中的PIC区域结构那样重新排列该信息。 As described above, it means that when all the information acquired in the high frequency modulated PIC area may rearrange the image information of the PIC area in FIG. 3 structure.

下文会详细描述一种用于在PIC区域中配置盘片信息(DI)的方法。 Hereinafter will be described in detail one configuration of the PIC area in the disc information (DI) method is used.

在BD-RE/WO中,“一簇”表示最小记录单元,544个簇一起构成一个片段作为一个上部的记录单元,总共5个片段一起构成PIC区域。 In BD-RE / WO, the "cluster 'represents a minimum record unit, 544 clusters constitute one fragment with a recording unit of an upper, the PIC area together constitute a total of five segments. 在第一片段IF0的前头簇中记录盘片信息。 Disc information is recorded in the head cluster of a first fragment IF0. 在每一层中且以相应的光盘所准许的写入速度来记录多个盘片信息,并且一条盘片信息包括112个位字节。 In each layer and the corresponding writing speed to the optical disk to record a plurality of permitted disc information, and one disc information includes one hundred twelve bytes. 具体来讲,把由112个字节构成的盘片信息称为盘片信息(DI)帧。 Specifically, the disc information of 112 bytes is referred to as disc information (DI) frame. 此外,在剩余的帧中的各前头簇中重复地记录相同的盘片信息内容,由此能够应对盘片信息的丢失。 Further, each of the top clusters in the remaining frames in the repeatedly recorded same information content of the disc, it is possible to cope with loss of the disc information.

在各盘片信息内记录表示相应记录层的信息、表示写入速度的信息、以及与写入速度相对应的写入策略信息。 Within each disc information corresponding to recording information indicating the recording layer, information representing writing speed, and a corresponding writing speed write strategy information. 因此在相应的光盘的记录重放中使用这种信息,由此能够针对每个记录层和每种写入速度提供最佳写入功率。 Thus the use of this information in the appropriate recording and reproducing the optical disc, thereby enabling to provide optimal write power per recording layer and writing speed of each.

即,本发明的盘片信息(DI)的特征在于,提供由相应盘片所支持的特定的写入速度信息以及相关联的写入策略信息,更具体地讲,其特征在于,在相应盘片中存在多层记录层的情况下,通过指定的方法来提供由各记录层所支持的特定写入速度以及相关联的写入策略。 Specifically, disc information (DI) feature of the invention is to provide a specific writing speed information and write strategy information associated with the disc supported by the respective, and more specifically, wherein, in the corresponding disc in the presence of the film recording layers, each recording layer is provided by a specified method to support specific writing speed and write strategy associated.

盘片信息(DI)的具体配置涉及蓝光盘片(BD)的配置。 Disc information (DI) relates to a specific configuration of a Blu-ray disc (BD) configuration. 很明显,基于DVD的盘片可能具有不同于上述结构的一种配置。 Clearly, DVD based disc may have an arrangement different from the above structure. 具体来讲,例如,如果盘片信息(DI)的大小对应于BD的大小,则它就等价地是112个字节。 Specifically, for example, if the size of disc information (DI) corresponds to the size of the BD, it is the equivalent of 112 bytes. 然而,通过将相同记录层的盘片信息(DI)视作一个信息以便一次而非重复地提供共同的信息,便可以另外只针对每个写入速度来配置不同的写入策略。 However, by the same recording layer of the disc information (DI) and not once seen as a message to repeatedly provide a common information can additionally be configured only different write strategy for each write speed.

在下文中,参照附图会详细解释各种实施例,这些实施例对应于一种配置盘片信息的方法以及一种将特定信息等记录到根据本发明的盘片信息内的方法。 Hereinafter, explained in detail with reference to the accompanying drawings of various embodiments will be those corresponding to one embodiment of the method of configuring disc information and a method of recording specific information and the like within disc information according to the method of the present invention.

图4A到4E是根据本发明第一实施例记录光盘的盘片信息的图,其中在相应的盘片信息上记录由一个规范所界定的多个写入策略(WS)类型之一。 4A to 4E according to a first embodiment of the present invention, FIG recording disc information of an optical disc, wherein one of the recording strategy (WS) types defined by a specification of a plurality of write on the corresponding disc information.

图4A示出了根据本发明第一实施例记录光盘的盘片信息的概念。 4A shows a concept of recording disc information according to a first embodiment of an optical disk according to the present invention.

参照图4A,在盘片内记录多条盘片信息,各盘片信息的记录顺序是由顺序号来决定的,并且记录顺序是由1个字节来记录的。 4A, a disc recorded in a plurality of disc information, the record sequence of each disc information is decided by a sequence number, and the record sequence is recorded by 1-byte. 例如,在盘片信息的第5个字节中记录相应信息,它是指定的“DI块中的DI帧顺序号”字段,并用“00h,01h,02h,03h……”来简洁地表示。 For example, recorded in the fifth byte of disc information corresponding information, which is designated "DI block DI frame sequence number" field, and succinctly expressed by "00h, 01h, 02h, 03h ......".

即,按如下方式来定义第5个字节的信息。 That is, in the following manner to define the fifth byte of information. 首先,如果第5个字节的信息是“00h”,则“00h”意指第1条盘片信息和第一记录层“层0”的1倍速的盘片信息。 First, if the fifth byte of information is 1 × speed disc information "00h", then "00h" is meant an article the first recording layer and the disc information "layer 0". “01h”意指第2条盘片信息和第二记录层“层1”的1倍速盘片信息。 "01h" means an article 2 and a second disc information recording layer "layer 1" in a speed disc information. “02h”意指第3条盘片信息和第一记录层“层0”的2倍速的盘片信息。 "02h" means an article 3 and the first disc information recording layer "layer 0" 2 times speed disc information. 并且“03h”意指第4条盘片信息和第二记录层“层1”的2倍速盘片信息。 And "03h" means that article 4 and the second disc information recording layer "layer 1" 2x speed disc information.

因此,优先按记录速度排序来排列盘片信息,然后按每层记录层的排序配置盘片信息。 Therefore, preferentially in the recording speed of the disc information are arranged in ordered, sorted and each recording layer of the disc configuration information. 然而,这仅是示例性的。 However, this is only exemplary. 相反,在配置盘片信息时,记录层排序可以优先于记录速度排序。 Conversely, when configuring disc information, the recording layer in the recording speed sorting priority order.

此外,在盘片信息的特定区域中,例如,第L到第111个字节的、名为“写入策略参数”字段的区域中,记录与相应的盘片信息所意指的记录速度相互协作的写入策略(WS)。 Further, in a specific area in the disc information, e.g., the L to 111 bytes, called "write strategy parameters" field area, the recording speed of the recording disc information corresponding to the meaning of each collaboration write strategy (WS). 并且在另外的特定区域中,例如,名为“写入策略类型”字段的区域中,记录能够标识在第L到第111个字节中所记录的记录写入策略(WS)的类型或种类的标识信息。 And in further specific area, e.g., area named 'write strategy type "field, the recording can be recorded in the identifier L to 111 bytes of the recorded write strategy (WS) type or species the identification information.

考虑到“写入策略(WS)”的意思,一般通过拾取头(图10中的“11”)将激光束加在光盘内的记录层上修改记录层的介质性质来执行其记录操作。 Considering the "write strategy (the WS)" means, generally by a pickup ( '11' in FIG. 10) the laser beam applied to the recording layer in the optical disc medium to modify properties of the recording layer to perform recording operation. 因此,应该确定激光束的强度(写入功率)、写入脉冲、施加写入功率于其上的时间等。 Thus, should determine the intensity of the laser beam (writing power), the write pulse, the write time power is applied thereto. 通常,把上述确定的各种写入策略都命名为“写入策略(WS)”,并且把在特定的“写入策略(WS)”中所记录的具体内容命名为“写入策略(WS)参数”。 Typically, the above-identified various write strategies are named 'write strategy (WS)', and the specific content in a specific "write strategy (WS)" recorded named "write strategy (WS )parameter".

在本发明中使用的写入策略(WS)参数意指与写入策略(WS)相关联的全部信息。 Write strategy (WS) used in the present invention means a write strategy parameters (WS) associated with all the information. 而WS参数意指配置WS的项与具体数值,并且是一种WS信息。 WS parameters means items and specific numeric WS configuration, and a WS information. 因此,WS信息具有包括上述“WS类型”、随后会解释的“WS标记”等、以及WS参数的包括性的概念。 Thus, having the information including the above WS 'WS Type', it will be explained later in 'WS flag "and the like, and the concept inclusive WS parameters.

可以用多种方式来记录写入策略(WS)。 You can use a variety of ways to record a write strategy (WS). 随着盘片密度越来越高且运行速度越来越快,写入速度,即盘片RPM,以及记录层的介质性质都受到相当大地影响。 With the increasing density and disk run faster and faster, writing speed, i.e., the RPM disc, and the dielectric properties of the recording layer have been considerably affected. 因此,要求更为精确的系统。 Therefore, a more accurate system requirements. 各种写入策略(WS),即WS类型,会在下文中得到解释。 Various write strategy (WS), i.e., WS types, will be explained below.

首先,有一种具有大量记录脉冲的系统,这些记录脉冲比形成于记录层介质上的记录条纹尺寸(n)小1,可把这称为“(n-1)WS”。 First, there is a system having a large number of recording pulses, the recording pulse ratio stripe formed on the recording size (n) on the recording medium layer of a small, this may be referred to as "(n-1) WS". 例如,如果条纹长度为7T,则根据(n-1)WS,要求6个脉冲来形成该7T。 For example, if the line length of 7T, according to the (n-1) WS, requires 6 pulses to form the 7T. 在这种情况下,各个写入脉冲的时间或写入功率的等级都是由相应盘片信息中所记录的写入策略参数来定义的。 In this case, write power level or the time of each write pulse from the corresponding write strategy parameters are the information recorded in the disc defined. 其次,有一种具有大量记录脉冲的系统,这些记录脉冲的尺寸等于记录条纹尺寸(n)的一半,可把这称为“n/2 WS”。 Secondly, there is a system having a large number of recording pulses, the recording size of these pulses is equal to half the recording stripe size (n), and this may be referred to as "n / 2 WS". 例如,如果条纹长度为7T,则根据(n-1)WS,要求3个脉冲来形成该7T。 For example, if the line length of 7T, according to the (n-1) WS, requires 3 pulses to form the 7T. 即,舍弃所得结果的小数部分,只有整数个脉冲是可用的。 That is, discard the fractional part of the result, only an integer number of pulses is available. 在这种情况下,各个写入脉冲的时间或写入功率的等级是由相应盘片信息中所记录的写入策略参数所定义的。 In this case, write power level or the time of each write pulse is the write strategy parameters recorded in the corresponding disc information as defined. 对应于各写入策略类型的各写入策略参数可以彼此之间具有不同的值。 Write strategy type corresponding to each of the respective write strategy parameters may have different values ​​from each other. 此外,不断开发出新的写入策略(WS)。 In addition, and constantly develop new write strategy (WS). 关于不同类型的写入策略(WS),当存在写入策略(WS)的各种系统(作为应用于彼此不同的写入策略(WS)的参数而存在)时,盘片制造商根据写入策略(WS)来测试写入功率,然后将测试的结果记录到盘片信息内第L到第111个字节的“WS参数”字段中,并且将WS类型信息记录到第N个字节中。 Of the different types of write strategies (WS), when there is a write strategy (WS) of the various systems (as different from each other applied to the write strategy (WS) parameters exist), according to the disc manufacturer writes strategy (WS) to test write power, and then the results of the test disc information recorded in the L th byte to the 111th "WS parameters' field, and the WS type information is recorded into the first N bytes .

如果存在N个类型的写入策略(WS),则标识信息将具体的识别值分配给各写入策略(WS)以便定义如下。 If N write strategy types exist (WS), the identification information identifying a specific value allocated to each write strategy (WS) to define as follows. 例如,“0000 0001b”意指第1个WS(写入策略-1或WS-1)。 For example, "0000 0001b" means the 1st the WS (write strategy 1 or WS-1). “0000 0010b”意指第2个WS(写入策略-2或WS-2)。 "0000 0010b" means the WS second (-2 or write strategy WS-2). “XXXXXXXXb”意指第N个WS(写入策略-N或WS-N)。 "XXXXXXXXb" means the WS N-th (or -N write strategy WS-N).

在本发明中,第1个WS(WS-1)是由上述“(n-1)WS”来定义的,第2个WS(WS-1)是由“(n/2)WS”来定义的。 In the present invention, first a WS (WS-1) is by the "(n-1) WS" defined, 2nd WS (WS-1) is defined by "(n / 2) WS" of.

此外,如果将“WS类型”设置成“0000 0000b”,则可将它定义成意指具体的WS类型以及WS参数并不存在于盘片信息内。 Further, if the 'WS Type "is set to" 0000 0000b ", it can be defined to mean the specific type of WS and WS parameters within disc information does not exist. 即,可使用第N个字节的“WS类型”字段作为表示不存在WS参数的信息以及用于指定WS类型的信息。 That is, using the N-th byte "WS Type 'field as information indicating the absence of WS parameters for specifying the type of WS information.

图4B示出了记录用于特定写入策略(WS)的盘片信息的一个实例,其中,在将用于1倍速的写入策略(WS)记录到第一记录层的1倍速盘片信息内的过程中,盘片制造商选择各种规范来记录第1个WS(WS-1)。 4B shows one example of a record for a specific write strategy (WS) the disc information, wherein the write strategy for 1x speed (WS) recorded in the disc information of lx speed of a first recording layer in the process, a disc manufacturer records selecting various specifications to a WS (WS-1).

即,如果盘片信息的第N个字节的“WS类型”字段为“000 0001b”意味着第1个WS(WS-1),则把与WS-1相对应的参数值写入第L到第111个字节的“写入策略参数”字段中。 That is, if the first N bytes of the disc information "the WS Type 'field" 000 0001b "means the 1st the WS (WS-1), put the write parameter value corresponding to the WS-1 of L to 111 bytes "write strategy parameters" field.

因此,当盘片制造商选择记录第2个WS(WS-2)时,把“0000 0010b”写入“写入策略类型”字段中,并且将适合第2个WS的参数写入第L到第111个字节中。 Thus, when a disc manufacturer records selected second WS (WS-2), the "0000 0010b" write "write strategy type" field, and the write parameters for the second to L-th WS the first 111 bytes. 根据写入策略(WS)类型,写入第L到第111个字节中的参数具有彼此不同的数值。 The write strategy (WS) type, of the write parameter L to 111 bytes have different values ​​from each other. 之前确定相应的写入策略(WS)参数为适合盘片特征的指定信息,并提供给盘片制造商或系统设计者。 Before determining the corresponding write strategy (WS) parameters for a specified feature information for the disk, and provided to a disc manufacturer or a system designer.

图4C到4E示出了将上述写入策略(WS)记录到盘片信息之内的方法所对应的具体实施例。 FIGS. 4C to 4E show specific embodiments of the above-described write strategy (WS) recorded within the disc information of the corresponding method. 图4C和图4D示出了方法,该方法针对在制造盘片的过程中要记录的全部记录层和记录速度,可选性地选择写入策略(WS)。 4C and 4D show a method for all recording layers and the recording speed of the disc during manufacture to be recorded, selecting the optional write strategy (WS). 图4E示出了在特定的记录速度的情况中以强制的方式来记录之前确定的写入策略(WS)的方法。 4E shows a method to force a way to record a write strategy (WS) previously determined in the case of a specific recording speed.

为便于解释,假定盘片包括双层并且1倍速和2倍速应用于各记录层。 For ease of explanation, assume that the disk 1 and comprises a double-speed and 2-speed is applied to each recording layer.

图4C示出了一种情形,在该情形中,在全部记录层中和按全部的记录速度时,能够存在任意不同的记录写入策略(WS)。 4C shows a situation, in this case, all of the recording layers and the recording speed of the entire press, there can be any of various recording write strategy (WS). 例如,在“00h”中记录第一记录层“层0”的1倍速盘片信息作为盘片信息顺序,而选择第1个WS(WS-1)作为写入策略(WS)而加以记录。 For example, the first recording layer, "layer 0" speed disc information of a disc information sequence as "00h", the selected first one WS (WS-1) as a write strategy (WS) and recorded. 在“01h”中记录第二记录层“层1”的1倍速盘片信息,并且选择第2个WS(WS-2)作为写入策略(WS)而加以记录。 Recording a second information recording layer disc speed 1 "level 1" in "01h", and select the second WS (WS-2) as a write strategy (WS) and recorded. 在“02h”中记录第一记录层“层0”的2倍速盘片信息,并且选择第1个WS(WS-1)作为写入策略(WS)而加以记录。 Recording the first recording layer 2x speed disc information of "layer 0" in "02h", and select the first WS (WS-1) as a write strategy (WS) and recorded. 在“03h”中记录第二记录层“层1”的2倍速的盘片信息,并且选择第N个WS(WS-N)作为写入策略(WS)而加以记录。 Recording the second recording layer, "layer 1" 2 × speed disc information of "03h", and the selected N-th WS (WS-N) as a write strategy (WS) and recorded. 在这种情况下,要用于第一记录层(层0)的1倍速的、对应于第1个WS(WS-1)的写入策略参数(例如,(n-1)写入策略类型)与要用于第一记录层(层0)的2倍速的写入策略参数可以具有不同值。 In this case, to be used for the first recording layer (Layer 0) 1 times speed, write strategy parameters corresponding to the first one WS (WS-1) (e.g., (n-1) write strategy type ) double-speed write strategy parameters with a first recording layer (layer 0) to be used may have different values.

图4D示出了能够可选性地记录写入策略(WS)的另一个实例,其中相同类型的写入策略(WS)应用于全部记录层和记录速度的盘片信息。 FIG 4D shows the writing can optionally record another example of the strategy (WS), wherein the same type of write strategy (WS) is applied to the entire disc information recording layer and the recording speed. 在这种情形中,用于特定记录层和/或写入速度的写入策略参数可以分别具有与其它记录层和/或写入速度所对应的不同的值。 In this case, for specific recording layer and the write strategy parameters / or writing speed may have different values ​​and the other recording layer and / or writing speed respectively corresponding.

即,由于能够可选地记录写入策略,盘片制造商能够将一个最可靠的写入策略(WS)完全相同地应用于全部盘片信息。 That is, it is possible to record a write strategy optionally, a disc manufacturer can be the most reliable write strategy (WS) applied to the entire disc information identically. 并且图4示出了一种情形,即在全部盘片信息中记录第1个WS(WS-1)。 And FIG. 4 shows a case where the recording of a WS (WS-1) in the entire disc information.

图4E示出了一种方法,用于在特定记录速度的情况下以强制方式记录之前确定的写入策略(WS)或在其余记录速度的情况下选择性地确定的写入策略(WS)。 4E shows a method for recording a write strategy previously determined in a mandatory manner in case of a specific recording speed (WS), or in the case of the remaining recording speed is selectively determined write strategy (WS) . 通常,1倍速的写入策略(WS)是指定的决定之前确定的那个特定方法的最重要的写入策略,并且盘片制造商能够选择性地记录除1倍速之外的其余记录速度。 Typically, a speed write strategy (WS) is the most important write strategy of the particular method previously determined specified decision and a disc manufacturer can selectively record the rest recording speed other than 1-fold speed. 然而,对于高速盘片而言,很明显,以强制方式确定的记录速度可以是2倍速或3倍速等以及1倍速。 However, for high-speed disc, it is obvious to forcibly determined recording speed may be 2 or 3, speed 1 and speed like speed. 例如,如果强制对应于1倍速的写入策略(WS)类型是第1个WS(WS-1),则在“00h”和“01h”中写入第一记录层的1倍速所对应的盘片信息作为盘片信息顺序,而应该以强制的方式写入第1个WS(WS-1)作为写入策略(WS)。 For example, if the force corresponding to a speed write strategy (WS) type is of a WS (WS-1), corresponding to the write speed of the disk 1 in the first recording layer "00h" and "01h" in sheet information as the disc information sequence, but should be forced manner a first write WS (WS-1) as the write strategy (WS). 在“02h”和“03h”中写入第一记录层的2倍速所对应的盘片信息,并且选择第2个WS(WS-2)并将其作为可以选择地记录的写入策略(WS)来加以记录。 Disc information corresponding to the writing speed of the first recording layer 2 in the "02h" and "03h", and select the second WS (WS-2) and as a write strategy can be optionally recorded (WS ) to be recorded. +因此,如果强制对应于1倍速的写入策略(WS)类型是第2个WS(WS-2),则很明显,应该以强制的方式在1倍速的盘片信息也记录于其上的“00h”和“01h”中记录第2个WS(WS-2)作为盘片信息顺序。 + Therefore, if forced to a speed corresponding to the write strategy (WS) is the second type WS (WS-2), it is clear that, should a forced manner in the disk speed information is also recorded thereon "00h" and "01h" is recorded in the second WS (WS-2) as a disc information sequence.

当应用图4所示情形时,以强制方式将多个指定的写入策略之一作为1倍速写入策略(WS)一致地写入,因此能够保护更多的盘片记录特征。 When the application situation shown in FIG. 4, a forced manner into one of a plurality of specified write strategies as one speed write strategy (WS) written in unison, it is possible to protect more disc recording characteristics. 盘片制造商能够一致地针对除1倍速之外的其余的记录速度来选择性地记录多个指定的写入策略之一,由此可以缩短盘片制造过程的时间。 Disc manufacturer can be uniformly for the rest recording speed other than the speed 1 to selectively record one of a plurality of specified write strategy, whereby a disc manufacturing process time shortened. 此外,在图4E所示的具体情形中,也能够记录用于1倍速的强制的写入策略(WS),并且盘片制造商能够单独选择性地记录用于1倍速的其它写入策略(WS)。 Further, in the specific case shown in FIG. 4E, it is possible to record the mandatory write strategy for 1x speed (the WS), and a disc manufacturer can be separately selectively record other write strategy for 1x ( WS). 在这种情况下,用于1倍速的盘片信息可以包括含指定的强制性写入策略(WS)在内的盘片信息,以及含选择性的写入策略(WS)在内的不同的盘片信息。 In this case, disc information for 1x speed can include disc information including the specified mandatory write strategy (WS), including, containing, and selectively write strategy (WS) including different disc information. 这在本发明的第三实施例的描述中会加以详细描述。 This will be described in detail in the description of the third embodiment of the present invention.

图5A到5C是根据本发明第二实施例来记录盘片信息的另一个示例的图,其中在相应盘片信息之内记录“可应用的写入速度信息”和“盘片内存在的记录层信息”以及由规范所定义的多种类型的写入策略(WS)之一。 5A to 5C are diagrams of another example of recording disc information according to a second embodiment of the present invention, "the applicable writing speed information 'where disc information recorded in the corresponding sum" memory recording disk layer information, "and a plurality of types of specifications defined by the write strategy (WS) one.

参照图5A,把“在DI块中DI帧顺序号”提供给各盘片信息的第5个字节以意指顺序,这意味着盘片信息是按与图4A的方式相同的特定顺序来配置的。 Referring to Figure 5A, the "DI frame in DI block sequence number" to the fifth byte of each disc information to mean a sequence, which means that disc information is the same manner of FIG. 4A particular order configuration. 把“写入策略类型(WS)”字段提供给盘片信息内一特定区域(第N个字节),以记录应用于相应盘片信息的WS的类型。 The "write strategy type (WS) 'field is provided to a specific area (N th byte) within disc information to record the type of WS applied to the corresponding disc information.

此外,在盘片信息内指定的区域(第M个字节)内记录可由相应盘片应用的写入速度信息,把它称为“写入速度标记”字段。 In addition, specified in the disc information area (M th byte) information from the corresponding writing speed recorded disc applications, it is called 'writing speed flag' field. 例如,相应盘片是否可应用八种写入速度中特定的一种写入速度是由分配给它的具有1个字节的相同区域中的一位一位来表示的。 For example, if the corresponding disc eight kinds of applicable writing speed in a specific writing speed is assigned to a region having the same one it in one byte represented. 即,可以定义成,如果在全部位中位值是“0b”,则相应的写入速度是不可应用的(得不到支持的),如果该位值是“1b”,则相应的写入速度是可以应用的(得到支持的)。 That is, can be defined, if all the bits in the bit value is "0b", then the corresponding writing speed is not applicable (not supported) if the bit value is "1b", the corresponding write speed is applicable (supported in). 因此,在1个字节内位b0到b7中的每一个都变为用于表示有或无特定的写入速度的可应用性的标记信息。 Thus, each of the bits b0 to b7 are used to become expressed or applicability of the free labeled specific writing speed information in one byte.

例如,如果只有相应盘片可以使用1倍速,则在第N个字节内写入“00000001”。 For example, if only the corresponding disc speed may be used, the write "00000001" in the first N bytes. 如果全部八种写入速度都是可用的,则在第N个字节内写入“11111111”。 If all of the eight kinds of writing speeds are available, the writing "11111111" in the first N bytes.

在上面的解释中,由每个盘片使用的1倍速和2倍速几乎都是之前确定要采用的。 In the above explanation, 1x and 2x speed prior to use almost all determined by each disk to be used. 然而,可以使用由规范所确定的写入速度作为自第三写入速度的其余写入速度。 However, write speed may be used as determined by the specification from the third rest writing speed of the writing speed. 例如,可能将第3、第4、第5、第6、第7和第8写入速度分别设置成5倍速、6倍速、8倍速、12倍速、14倍速和16倍速。 For example, it may be the third, fourth, fifth, sixth, seventh and eighth write speeds are set to 5 times speed, 6-times speed, 8x, 12x, 14 and 16x speed.

同时,在盘片信息内另一个特定区域中(第L个字节)记录表示在相应盘片内存在的记录层数目的记录层信息,把它称为“记录层的数目”字段。 Meanwhile, in another specific area (L th byte) within the disc information recorded in the memory indicates the respective recording layers of the disk recording layer information object, it is called "the number of recording layers" field. 例如,表示记录层数目的值可以在具有分配给它的1个字节的相同区域中用二进制数来表示。 For example, the value represents the number of recording layers object can be represented by a binary number in the same area having allocated to it a byte. 万一记录层是图1所示的单层,在第L个字节中写入“0000 0001”。 In case the recording layer is a single layer as shown in FIG. 1, is written in the L th byte "00000001." 万一记录层是图2所示的双层,在第L个字节中写入“0000 0010”。 In case a double recording layer shown in FIG. 2 is written in the L th byte "00000010." 万一存在四层记录层,在第L个字节中写入“0000 0100”。 In case the presence of four recording layers written in the L th byte "00000100."

既然对当前所考虑的记录层的数目加以限制,目前是两层记录层,那么第L个字节内的4-位就足够表示总共15层记录层了(假设“1111”)。 Since the restrictions on the number of recording layers is currently considered, is currently two recording layers, then the 4-position in the first byte sufficient L represents a total of 15 recording layers (assuming "1111"). 在这种情况下,很明显,在第L个字节的其余区域(4-位)中可以写入其它有效信息。 In this case, it is clear that other valid information can be written in the remaining region of L bytes (4 bits).

此外,给另一个特定区域(第P到第111个字节)提供与第N个字节的“写入策略(WS)类型”字段值相协作的特定的“写入策略(WS)参数”字段以便将相关信息记录于其中。 Further, to another specific area (P th byte to 111) provides specific "write strategy (WS) parameters 'cooperate with the" write strategy (WS) Type' field value of the N th byte fields for recording the information therein.

因此,从上面记录的第M个字节中的“写入速度信息”和第L个字节中的“记录层信息”中,记录重放装置(图9)识别在相应盘片之内存在多少盘片信息。 Thus, the first M bytes from the above record in the "writing speed information 'of the L th byte and the' recording layer information ', the recording and reproducing apparatus (FIG. 9) of the disk identifying a respective memory how much disc information. 即,通过将可应用的写入速度数目乘以记录层的数目来找出存在的盘片信息的数目。 That is, to find the number of disc information exist by the number of writing speed applicable by multiplying the number of recording layers.

当本发明将一个写入策略(WS)应用于特定写入速度和特定记录层时,在确定盘片信息数目的过程中可能并不考虑写入策略(WS)的种类(类型)和数目。 When the present invention is a write strategy (WS) applied to a specific writing speed and a specific recording layer in disc information number determining process may not be considered for inclusion in the kind (type) strategy (WS) and the number. 然而,在本发明的第三实施例中(图6到图8),将要描述对应于特定的写入速度和特定的记录层可存在多个写入策略(WS)。 However, in the third embodiment of the present invention (FIG. 6 to FIG. 8), will be described there may be a corresponding plurality of write strategy (WS) to a specific writing speed and a specific recording layer. 在这种情况下,存在盘片信息的总数并不总是通过将可应用的写入速度数目乘以记录层的数目来得到。 In this case, the total number of disc information is not always present by the number of recording layers applicable writing speed is obtained by multiplying the number. 这在图6中将详细解释。 This will be explained in detail in FIG. 6.

因此,上面确定的多个盘片信息的顺序是由顺序号来决定的,在上文的描述中它被写入第5个字节中,并且盘片信息中的每一个按该顺序指明之前确定的写入速度和记录层。 Therefore, before a plurality of disc information sequence is determined by the above-determined sequence number, in the above description it is written in the fifth byte, and each disc information indicates this order determining the writing speed and recording layer.

例如,已经知道,如果第N个字节是“0000 1111”则存在盘片可应用四种写入速度,如果第L个字节是“0000 0010”则该盘片内存在两层记录层,需要总共八条盘片信息,所以该顺序将是“00h到07h”。 For example, it is known if the N-th byte is '0000 1111' is present four kinds of applicable writing speed disc, if the L th byte is '0000 0010' is recorded in the two-layer disk memory, It requires a total of eight disc information, so the order will be "00h to 07h". 之前所确定的是,盘片信息“00h”、“0 1h”、“02h”、“03h”、“04h”、“05h”、“06h”和“07h”涉及“1倍速,第1记录层”、“1倍速,第2记录层”、“2倍速,第1记录层”、“2倍速,第2记录层”、“第3写入速度,第1记录层”、“第3写入速度,第2记录层”、“第4写入速度,第1记录层”以及“第4写入速度,第2记录层”。 Previously determined that disc information "00h", "0 1h", "02h", "03h", "04h", "05h", "06h" and "07h" relates to "speed 1, the first recording layer "," 1 speed, the second recording layer ',' 2x speed, the first recording layer ',' 2x speed, 2nd recording layer "," third writing speed, the first recording layer, "" writing, the third speed, 2nd recording layer "," the fourth writing speed, the first recording layer, "and" the fourth writing speed, the second recording layer. "

因此,为了获取用于特定目标写入速度和特定目标记录层的盘片信息,促使记录重放装置(图10)从通常记录在各个盘片信息之内的第N个字节的“写入速度信息”和第L个字节的“记录层信息”来检查哪一条盘片信息与特定目标写入速度和记录层有关,这样不必通过重放来检查全部的盘片信息。 Accordingly, in order to acquire the disc information for a specific target writing speed and a specific target recording layer, the reproducing apparatus causes the recording (FIG. 10) from the N-th byte commonly recorded within the respective disc information of the "write speed information "and the L-th byte of the" information recording layer "to check which disc information and a specific target writing speed and recording layer relating to such disc is not necessary to check all of the information reproduced.

图5B示出了根据图5A中的本发明第二实施例记录盘片信息的实例。 5B shows an example of recording disc information of the second embodiment according to the embodiment of the present invention in FIG. 5A. 可以知道,在通常记录于全部盘片信息中的第M个字节(“0000 0011b”)中,有两种(1倍速,2倍速)可应用的写入速度。 Can know, at all in the normal recording disc information in the M th byte ( "0000 0011b"), there are two kinds of write speed (1 times speed, double speed) can be applied. 因此,在图5B的示例中,存在总共四条盘片信息(两层记录层×两种写入速度),并且盘片信息的顺序变为'00h'(1X,L0)→'01h'(1X,L1)→'02h'(2X,L0)→'03h'(2X,L1)。 Thus, in the example of FIG. 5B, there are a total four disc informations (two recording layers × two writing speeds), and the order of the disc information becomes '00h' (1X, L0) → '01h' (1X , L1) → '02h' (2X, L0) → '03h' (2X, L1). 这是根据预定顺序由指定内容来完成的。 This is a specified content according to a predetermined sequence to complete. 因此,应该根据上述方式来配置全部的盘片信息以使使用的相互兼容性成为可能。 Thus, all should be configured based on the information disc so that the embodiment becomes possible to use mutual compatibility.

在各盘片信息之内记录固有的写入策略(WS)。 Record intrinsic write strategy (WS) in each of the disc information. 具体来讲,在第N个字节中记录写入相应盘片信息内第P到第111个字节中的写入策略(WS)类型信息。 Specifically, in the N th byte within the corresponding disc information is written record of P to 111th byte write strategy (WS) type information. 即,在每一个盘片信息中,在第N和第P到111个字节中的信息可以有所不同,这意味着盘片制造商能够选择性地记录多个WS之一。 That is, each of the disc information, the information in the N and P to 111 bytes can vary, which means that a disc manufacturer is capable of selectively recording one of a plurality WS.

在图5B的示例中,'00h(1X,L0)'和'01h(1X,L1)'涉及第一类型写入策略(WS-1)的应用,而'02h(2X,L0)'和'03h(2X,L1)'涉及第二类型写入策略(WS-2)的应用。 In the example of FIG. 5B, '00h (1X, L0)', and '01h (1X, L1)' apply a first write strategy type (WS-1) is directed, and '02h (2X, L0)' and ' 03h (2X, L1) 'relates to the application of a second type write strategy (WS-2) a.

图5C示出了根据图5A中本发明的第二实施例记录盘片信息的另一个实例。 Figure 5C shows another example of recording disc information of a second embodiment of the embodiment of the present invention in FIG. 5A. 从通常在全部盘片信息中记录的第M个字节('1111 1111b')可知有八种(1X,2X,……16X)可应用的写入速度,并且从第L字节('0000 0100b')可知盘片内存在四层记录层。 M byte from the normally recorded in all the disc information ( '1111 1111b') have found eight kinds of write speed (1X, 2X, ...... 16X) applicable, and from the L byte ( '0000 0100b ') found that four recording layers exist within a disc.

因此,在图5C的另一个示例中,存在总共32条盘片信息(四层记录层×八种写入速度),并且盘片信息的顺序变为'00h'(1X,L0)→'01h'(1X,L1)→'02h'(1X,L2)→'03h'(1X,L4)→'04h'(2X,L0)→…→'31h'(16X,L4)。 Thus, in another example of FIG. 5C, there are a total of 32 disc information (four recording layers × eight kinds of writing speeds), and the order of the disc information becomes' 00h '(1X, L0) →' 01h '(1X, L1) →' 02h '(1X, L2) →' 03h '(1X, L4) →' 04h '(2X, L0) → ... →' 31h '(16X, L4). 这是根据预定顺序由指定内容来完成的。 This is a specified content according to a predetermined sequence to complete. 因此,应该根据上述方式来配置全部的盘片信息以使使用的相互兼容性成为可能。 Thus, all should be configured based on the information disc so that the embodiment becomes possible to use mutual compatibility.

在图5C的另一个示例中,如果记录重放单元(图10)打算搜索与第一记录层的2倍速(2X,L0)有关的盘片信息以便通过在相应盘片信息内应用写入策略(WS)来进行记录,则从全部盘片信息中所记录的第M和第L字节的信息可以知道,在根据诸如'00h'(1X,L0)→'01h'(1X,L1)→'02h'(1X,L2)→'03h'(1X,L4)→ '04h'(2X,L0)→……→'31h'(16X,L4)根据的盘片信息顺序可以是'00h'(1X,L0)→'01h'(1X,L1)→'02h'(2X,L2)→'03h'(2X,L4)→'04h'(2X,L0)→……→'31h'(16X,L4)的盘片信息顺序的相应盘片中存在总共32条盘片信息。 In another example of FIG. 5C, if a record playback unit (FIG. 10) intends to 2x speed (2X, L0) and disc information related to the search for the first recording layer by applying a write strategy within the corresponding disc information (WS) to be recorded, from the information of the L and M bytes of information recorded in the entire disc can be known, according to such as '00h' (1X, L0) → '01h' (1X, L1) → '02h' (1X, L2) → '03h' (1X, L4) → '04h' (2X, L0) → ...... → '31h' (16X, L4) in accordance with the order of disc information can be '00h' ( 1X, L0) → '01h' (1X, L1) → '02h' (2X, L2) → '03h' (2X, L4) → '04h' (2X, L0) → ...... → '31h' (16X, There are a total 32 corresponding disc information disc L4) in the disc information sequence. 因此,记录重放装置(图9)能够识别,与要搜索的第一记录层的2倍速(2X,L0)有关的盘片信息是'04h',并且相应的盘片信息('04h')是作为来自写入策略(WS)类型标识信息('0000 0001b')(该标识信息被记录在相应信息('04h')之内)的第一类型写入策略(WS-1)而加以记录的,,由此通过第P到第111个字节来读出第一类型写入策略(WS-1)的参数值以在记录中利用。 Thus, the recording and reproducing apparatus (FIG. 9) can be recognized, and the first recording layer to be searched 2x speed (2X, L0) relating to a disc information '04h', and the corresponding disc information ( '04h') as (WS) type identification information from the write strategy ( '0000 0001b') (the identification information is recorded in the corresponding information ( '04h') within) a first type write strategy (WS-1) is recorded while ,, thereby reading the first 111 bytes of P to the first type write strategy parameters (WS-1) to utilize in the recording.

同样,如果打算搜索与第四记录层的16倍速(16X,L3)有关的盘片信息以便通过在相应盘片信息内应用写入策略(WS)来执行记录,则记录重放单元(图9)通过相同的过程来识别相应的盘片信息是'31h'并且写入策略类型(WS)是第二类型(WS-2),由此能够在记录过程中使用它们。 Similarly, if the intended 16x (16X, L3) and the fourth search disc information related to the recording layer so as to perform recording by applying a write strategy within the corresponding disc information (the WS), the record playback unit (FIG. 9 ) to identify the corresponding disc information by the same procedure is '31h' and the write strategy type (WS) is the second type (WS-2), whereby they can be used in the recording process.

图6到8示出了根据本发明第三实施例记录光盘的盘片信息的方法。 FIGS 6-8 illustrate a method of recording disc information of an optical disc according to a third embodiment of the present invention. 本发明的第二实施例的特征在于,对于相同的写入速度/记录层,配置至少一种写入策略(WS)。 The second embodiment of the present invention is characterized in that, for the same writing speed / recording layer disposed at least one write strategy (WS). 即,可以存在与相同的写入速度/记录层相关联的多条盘片信息,它们可分别按WS类型来分类。 That is, there may be the same writing speed / recording layer plurality of disc informations associated, respectively, they may be classified by WS types.

图6示出了根据本发明第三实施例记录光盘的盘片信息的方法的概念。 Figure 6 illustrates the concept of a method of recording disc information of an optical disc according to a third embodiment of the present invention.

参照图6,盘片信息的每个顺序分别由顺序号来确定并由1个字节来记录。 Referring to Figure 6, each disc information sequence is determined by the respective sequence number recorded by one byte.

例如,在盘片信息内第5个字节中记录信息,被称为“DI块中的DI帧顺序号”,并被简写为'00h,01h,02h,……'。 For example, the information recorded in the disc information of five bytes, is referred to as "DI block DI frame sequence number", and is abbreviated as '00h, 01h, 02h, ......'. 即,如果第5字节的信息是'00h',则它的意思是第1条盘片信息。 That is, if the information of the 5th byte is '00h', it means that the article 1 of the disc information. 如果第5字节的信息是“07h”,则它的意思是第8盘片信息。 If the information of the fifth byte is "07h", it means that the eighth disc information.

在配置盘片信息的过程中,本发明的特征在于,对应于每种写入速度、每种记录层和每种写入策略(WS),单独提供盘片信息,并且根据预定方式一致地确定多个单独提供的盘片信息的配置顺序。 In the process of configuring disc information, the present invention is characterized in that, corresponding to each writing speed, the recording layer of each and every write strategy (the WS), separately provided disc information, and determines a consistent manner according to a predetermined a plurality of configuration sequence of the disc information is separately provided.

例如,如果相应光盘包括一对记录层并存在多个WS类型,则可以按下面的方式配置盘片信息。 For example, if a corresponding optical disc includes a recording layer and a plurality of WS types exist, disc informations can be configured in the following manner.

第1盘片信息的'00h'与1倍速、第一记录层L0以及WS1有关。 '00h' of 1 × speed, the first recording layer L0, and WS1 to a first disc information. 第2盘片信息的'01h'与1倍速、第一记录层L0和WS2有关。 '01h' of 1 × speed, the first recording layer L0, and WS2 For the second disc information. 第3盘片信息的'02h'与1倍速、第2记录层L1和WS 1有关。 The third disc information '02h' and 1 speed, the second recording layer L1 and the WS 1 related. 第4盘片信息的'03h'与1倍速、第2记录层L1以及WS2有关。 '03h' of 1 × speed, the second recording layer L1, and WS2 to a fourth disc information. 第5盘片信息的'04h'与2倍速第一记录层L0以及WS1有关。 '04h' of 2 × speed of a first recording layer L0, and WS1 5 disc information related. 第6盘片信息的'05h'与2倍速和第1记录层L0以及WS3有关。 '05h' and 2 and the speed of the first recording layer L0, and WS3 a sixth disc information. 第7盘片信息的'06h'与2倍速、第2记录层L1以及WS1有关。 Seventh disc information '06h' and 2 speed, the second recording layer L1, and WS1 related. 以及第8盘片信息的'07h'与2倍速、第2记录层L1以及WS3有关。 And '07h' and 2 speed, the second recording layer L1, and WS3 For eighth disc information.

即,在配置盘片信息的过程中,根据本发明的第三实施例的特征在于,每种写入速度配置至少一条盘片信息,每一记录层重新配置各个写入速度盘片信息,并且向每一记录层提供至少一种WS类型。 That is, the process of configuring disc information, according to the features of the third embodiment of the present invention, each of the at least one configuration writing speed disc information, each recording layer reconfigure each writing speed disc information, and providing at least one WS type to each recording layer.

由此,在为相同的写入速度/记录层配置盘片信息的过程中,可以根据WS类型来配置多个盘片信息。 Thus, in the process for the same writing speed / recording layer configuring disc information, disc information can be configured according to the plurality of WS types.

图7A示例性地示出了一种根据图6的本发明第三实施例来配置盘片信息的方法。 FIG. 7A exemplarily shows a method of configuring disc information according to a third embodiment of the present invention, FIG. 6.

参照图7A,把“DI块中的DI帧顺序号”提供给各盘片信息的第5个字节,以表示顺序,这意味着盘片信息是以图6中优先级的特定顺序来配置盘片信息的(写入速度→记录层→ WS类型)。 Referring configured to Figure 7A, the "DI frame sequence DI block number" to the fifth byte of each disc information to indicate the order of priority in a specific order which means that disc information is FIG. 6 disc information (writing speed → recording layer → the WS type).

并且,分别在第N、第M、第L、以及第P到第111个字节之中记录“写入策略(WS)类型”字段(第N个字节)、“写入速度标记”字段(第M个字节)、“记录层的数目”字段(第L个字节)以及“写入策略(WS)参数”字段(第P到第111个字节)。 And it was recorded "write strategy (WS) Type 'field (N th byte) Among the N, M first, second L, and P th byte to 111th," writing speed flag' field (M th byte), 'the number of recording layers "field (L th byte) and' write strategy (WS) parameters' field (P th byte to 111th). 记录在这些字段中的各信息的意义与第二实施例(图5A)相同。 Meaning of each information recorded in these fields of the second embodiment (FIG. 5A) the same.

在图7中,第M个字节的'写入速度标记=0000 0111b'意味着可以应用三种类型的写入速度。 In Figure 7, the M-byte 'writing speed flag = 0000 0111b' means that the application of three types of writing speed. 并且第L字节的'记录层数目=0000 0010b'意味着存在两层记录层。 And 'the number of recording layer = 0000 0010b' of L th byte means two recording layers exist.

此外,在盘片信息内另一个特定区域中(第K个字节)记录用于通知写入策略(WS)可由相应盘片通过规范来应用的信息,这被称为'写入策略(WS)标记'字段。 Further, in another specific area (K th byte) within the disc information for notifying the recording write strategy (WS) information from the corresponding disc specification of the application, which is referred to as' write strategy (WS ) flag 'field. 例如,八种写入策略(WS)类型中特定的一种写入策略(WS)是否可由相应盘片来应用是在分配给它的具有1个字节的相同区域中由1-位来表示的。 For example, eight kinds of write strategy (WS) type in a specific write strategy (WS) whether corresponding disc may be applied in the same region assigned to it having a byte in the 1-position is represented by of. 即,可以定义成,如果在全部位中位值是'0b'则相应的写入策略(WS)不是可应用的,或者如果该位值是'1b'则相应的写入策略(WS)是可以应用的(得到支持的)。 That is, can be defined as, if the corresponding write strategy (WS) in all bits median is '0b' is not applicable, or if the bit value is '1b', the corresponding write strategy (WS) is It can be applied (to be supported). 由此,1个字节之内每个位b0到b7变为标记信息,用于表示特定的写入策略(WS)类型的有或无。 Thus, each of the bits b0 to b7 within 1-byte becomes flag information of, for indicating a specific write strategy (WS) type or absence. 例如,如果第1到第3写入策略(WS)类型WS1到WS3仅可由相应盘片来应用,则在第L个字节中写入'0000 0111b'。 For example, if the first to third write strategy (WS) types WS1 to WS3 be applied only by the corresponding disc, is written in the L th byte '0000 0111b'. 如果全部八种写入策略(WS)类型WS1-WS8都是可应用的,则在第L个字节中写入'1111 1111b'。 If all of the eight kinds of write strategy (WS) types WS1-WS8 are applicable, is written in the L th byte '1111 1111b'. 在图7A中,在第K个字节中写入'0000 1111b'以允许四种写入策略(WS)类型WS1-WS4。 Written in K th byte in FIG. 7A '0000 1111b' to allow the four kinds of write strategy (WS) types WS1-WS4.

通过分别写入第M、第L和第K字节信息(这些信息以对于全部盘片信息为共同的相同值记录在盘片信息中),促使记录重放装置(图10)获取相应盘片可应用的写入速度的信息、写入策略(WS)类型的信息和记录层的数目的信息,不管重放任何盘片信息。 By the first write M, L and K byte of information (information in common the same value for all the disc information recorded in the disk information), respectively, causes the recording and reproducing apparatus (FIG. 10) to obtain the corresponding disc writing speed information can be applied, the number of write strategy (WS) type information and the information recording layer, regardless of any disc information reproduction.

具体来说,在配置盘片信息的过程中,可能能够记录所有可由规范应用的写入策略(WS)类型。 Specifically, in the process of configuring disc information, it may be able to record a write strategy can be applied to all specifications (WS) type. 然而,在这种情况下,所记录的盘片信息的数目过量地增大。 However, in this case, the number of the recorded disc information excessively increases. 此外,盘片制造商应该测试全部的写入策略(WS)类型并将测试结果记录到盘片信息内,由此它变为一个负担。 In addition, a disc manufacturer should test the entire write strategy (WS) types and record the test results within the disc information, whereby it becomes a burden.

因此,在根据本发明的实施例中,比最大可应用写入策略类型的数目(n)要少的写入策略(WS)的数目(m)可以每种写入速度记录在盘片信息内,并且盘片制造商进一步能够选择性地记录多个写入策略(WS)中特定的一个,由此确保了盘片制造商的方便性,并能够有效地记录盘片信息。 Thus, in the embodiment of the present invention, the number (n) types of write strategies can be applied according to the ratio of the maximum number of less write strategy (WS) (m) of each of the writing speed can be recorded in a disc information and a disc manufacturer further capable of selectively recording a plurality of write strategy (WS) in a specific, thereby ensuring convenience of the disc manufacturer, and can be efficiently recorded disc information.

在图7A中,使用第1和第2类型写入策略WS1和WS2时,以1倍速(1X)来执行记录,使用第2和第3类型写入策略WS2和WS3,以2倍速(2X)来执行记录,或者使用第3和第4类型写入策略WS3和WS4,以3倍速(3X)来执行记录。 In FIG. 7A, using first and second type write strategies WS1 and WS2, the 1 × speed (1X) recording is performed, using the second and third types of write strategies WS2 and WS3, at 2x speed (2X) recording is performed, using the first or the third and fourth type write strategies WS3 and WS4, to speed 3 (3X) to perform recording.

即,对于每种写入速度,通过使用少于总的可应用写入策略(WS)类型(四种类型)的写入策略(WS)类型,可以记录盘片信息。 That is, for each writing speed, by using less than total applicable write strategy (WS) types (four types) write strategy (WS) type, disc information can be recorded. 并且,能够通过'写入策略(WS0类型字段(第N个字节))'和'写入策略(WS)参数'字段(第P到第111字节)来确认或证实应用于各盘片信息的固有写入策略(WS)。 And it is possible to verify or confirm applied by each disc 'write strategy (WS0 is Type field (N th byte))' and 'write strategy (WS) parameters' field (P th byte to 111) intrinsic write strategy information (WS).

图7B示出了根据图6的本发明第三实施例记录盘片信息的另一个实例。 FIG. 7B shows another example of recording disc information of the third embodiment according to the embodiment of the present invention in FIG. 6. 像图7A那样,存在三种可应用的写入速度,并且在第M个字节中写入'00000111b'。 Like FIG. 7A as the presence of three kinds of applicable writing speed, and write the M-byte '00000111b'. 存在四种可应用的写入策略类型,并且在第K个字节中写入'00001111b'。 The presence of four kinds of write strategy types applicable, and written in K th byte '00001111b'. 在盘片内存在两层记录层,并且在第L个字节中写入'0000 0010b'。 In the two recording layers exist within the disc, and writes the first byte in the L '0000 0010b'.

参照图7B,在使用多个可应用的写入策略(WS)之一来配置盘片信息的过程中,对于每个相同的写入速度和记录层,配置至少一条盘片信息。 7B, the process in one (WS) using a plurality of write strategy applicable to the configuration of the disc information for the same writing speed and per recording layer disposed at least one disc information. 在这样做的过程中,定义最优先提供的盘片信息为盘片制造商所提供的较佳的WS,而定义在该较佳的WS之后的另一条盘片信息为可选的WS。 In doing so, the most preferentially provided disc information is defined as a disc manufacturer provides the preferred WS, and defined after the preferred WS of the disc information to another optional WS.

即,盘片信息'00h'和盘片信息'01h'两者都涉及1倍速(1X)和第一记录层(L0)。 Specifically, disc information '00h' and disc information '01h' relates to both 1X speed (1X) and the first recording layer (L0). 然而,记录在'00h'中作为优先提供的盘片信息的WS1类型变为较佳的WS,而记录在'01h'中作为接下来提供的WS1类型信息变为可选的WS。 However, the recording in '00h' as ​​a disc information type WS1 priority provide the WS becomes the preferred, is recorded in '01h' as ​​next provided WS1 type information becomes optional WS.

盘片信息'04h'、盘片信息'05h'以及盘片信息'06h'涉及2倍速(2X)和第一记录层(L0)。 Disc information '04h', disc information '05h' and disc information '06h' relate to 2x speed (2X) and the first recording layer (L0). 然而,记录在'04h'中作为优先提供的盘片信息的WS2类型信息变为较佳的WS,而作为接下来提供的、记录在'05h'中的WS1类型信息和记录在'06h'中的WS3类型信息分别变为可选的WS。 However, the recording in '04h' as ​​the WS2 type information preferentially provided disc information becomes the preferred the WS, as provided in the next, and recorded WS1 type information recorded in '05h' in the '06h' in the WS3 type information respectively become optional WS. 即,它们可以应用于相同写入速度/记录层的至少三条盘片信息。 That is, they may be applicable to the same writing speed / recording layer, the at least three disc informations.

此外,盘片信息'10h'涉及第三种速度(3倍速)以及第1记录层(L0),并且盘片信息'11h' 涉及第三种速度(3倍速)以及第2记录层(L0)。 Moreover, disc information '10h' relates to the third speed (3 speed), and the first recording layer (L0), and disc information '11h' relates to the third speed (speed 3) and a second recording layer (L0) . 万一对相同记录速度/记录层而言只提供一种WS类型信息,则所提供的WS变为较佳的WS。 In case only one WS type information is provided for recording the same speed / recording layer, WS of the provided WS becomes the preferred.

即,当盘片制造商根据之前确定的规范在盘片内提供盘片信息时,光学记录重放装置(图9)以特定的顺序(写入速度→记录层)读出盘片信息。 That is, when a disc manufacturer provides disc information within a disc according to the previously determined specification, an optical record playback apparatus (FIG. 9) reads out the disc information in a specific order (writing speed → recording layer). 如果在相同写入速度/记录层上存在多个盘片信息,则光学记录重放装置(图10)将盘片信息内优先提供的WS识别为较佳的WS,并且将下一个WS识别为由盘片制造商所附加提供的可选WS,由此能够使用盘片信息有效地记录重放。 If a plurality of disc informations exist on the same writing speed / recording layer, the optical record playback apparatus (FIG. 10) identifying the WS within the disc information is preferentially provided in the preferred WS, and the next WS as identified Alternatively the WS additionally provided by a disc manufacturer, thereby enabling to effectively use the recording and reproducing disc information.

即便较佳的WS和可选的WS都是盘片制造商能够任意选择的“选择性的WS”,也有可能使较佳的WS成为'强制的WS',可选的WS成为'选择性的WS'。 Even if the preferred WS WS are optional and can be a disc manufacturer arbitrarily selected "selective WS", also it has the potential to become the preferred WS 'mandatory WS', becomes optional WS 'selectivity WS '.

图8示出了根据图6的本发明第三实施例记录盘片信息的另一个实例,其中盘片制造商直接以特定的写入速度提供最佳的写入策略(WS)类型信息。 FIG 8 shows another example of recording disc information of the third embodiment of the embodiment of the present invention, FIG. 6, wherein a disc manufacturer provides the best write strategy (WS) type information directly to a specific writing speed.

参照图8,分别在第N、第M、第K、第L和第P到第111个字节中记录'写入策略(WS)类型'字段(第N个字节)、'写入速度标记'字段(第M个字节)、'写入策略(WS)标记'字段(第K个字节)、'记录层的数目'字段(第L个字节)以及'写入策略(WS)参数'字段(第P到第111个字节)。 Referring to FIG. 8 write speed, respectively, the N, M first, second K, L and P of the 111th byte records' write strategy (WS) Type 'field (N th byte) is' flag 'field (M th byte),' write strategy (WS) flag 'field (K th byte),' the number of recording layers 'field (L th byte) and' write strategy (WS ) parameters' field (P th byte to 111th). 记录在这些字段中的各信息的意义与第二实施例(图7B)相同。 Meaning of each information recorded in these fields of the second embodiment (FIG. 7B) the same.

把'写入速度中最佳的WS标记'字段提供给盘片信息内另一个特定区域(第Q个字节),由此盘片制造商提供WS信息,该信息表示对于每个相同的写入速度而存在的多个写入策略(WS)中最佳质量的WS。 Providing the 'Best WS writing speed flag' field to another specific area (Q-th byte) within disc information, whereby a disc manufacturer provides information WS, for which the same write information indicating each the plurality of write strategies exist speed (WS) in the best quality WS. 例如,图8示出了第2个WS(WS2)是在特定写入速度下八种可应用的WS中“最佳的WS”。 For example, FIG. 8 shows a second WS (WS2) is the WS eight kinds of applicable writing speed at a specific "best WS."

当像图7A那样对于相同写入速度/记录层能够存在多个WS时,光学记录重放装置(图10)不能够区分哪一个是对应于相应写入速度的最适合的WS。 When / recording layer can exist as a plurality of WS as in FIG. 7A for the same writing speed, the optical recording reproduction apparatus (FIG. 10) is not able to distinguish which corresponding to the respective optimum writing speed WS. 因此,光学记录重放装置通过应用提供给盘片信息的全部WS来计算最佳WS。 Thus, the optical recording computes the optimal WS WS by all applications provided to the disc information reproducing apparatus. 然而,通过将“写入速度中最佳的WS标记”字段提供给第Q个字节,便可以优先地使用记录在第Q个字节中的WS。 However, through the "optimum writing speed WS flag 'field to the Q th byte provided, it can be preferentially used WS recorded in the Q th byte.

当像图7B那样对于相同写入速度/记录层能够存在多个WS时,可以通过一种之前指定的确定方法将记录在第1条盘片信息中的WS识别为较佳的WS。 When a plurality of can exist as WS as in FIG. 7B for the same writing speed / recording layer, the method can be determined by a method specified in section before recording a disc identification information as the preferred WS WS. 然而,通过将“写入速度中最佳的WS”字段提供给第Q个字节,也可以重新确认较佳的WS。 However, through the "optimum writing speed the WS 'field to the Q th byte provided, may reconfirm the preferred WS. 此外,当对于相同的写入速度/记录层而记录在第一盘片信息中的较佳的WS不同于第Q个字节的“写入速度中最佳WS标记”信息时,例如,如果较佳的WS是以强制方式确定的“强制性WS”,则把优先权给予盘片制造商所提供的第Q个字节的信息,由此以相同的写入速度在确定最佳WS的过程中能够更有效地提供信息。 Further, when the preferred WS for the same writing speed / recording layer is recorded in the first disc information is different from the first byte Q 'Best WS flag in writing speed "information, for example, if the preferred WS is defined forcibly 'mandatory WS', priority is given to put the information of the Q th byte provided by a disc manufacturer, thereby at the same writing speed in determining the optimal WS process information more effectively.

图9A到9E是根据本发明第四实施例记录控制信息的图。 9A to 9E is a fourth embodiment according to the present invention, FIG embodiment the recording control information. 记录控制信息取决于记录方法,比如CLV模式或CAV模式,其中用于识别盘片信息类型的信息,比如CLV模式或CAV模式,与另一条能够识别最终使用的写入策略(WS)类型的信息一起被记录在盘片信息内。 Recording control information depending on the recording method, such as CLV mode or CAV mode, in which information for identifying a type of disc information, such as the CLV mode or CAV mode, a write strategy with the other end-use can be identified (WS) type information It is recorded together in the disc information.

参照图9A,能够识别写入策略(WS)类型的信息是用来识别盘片制造商选择使用多种指定的写入策略(WS)中的哪一个,而用于识别盘片信息类型的信息能够识别相应的盘片信息是CLV模式还是CAV模式。 9A, the write strategy can be identified (WS) type information is information for identifying a disc manufacturer use various kinds of specified write strategy which (WS) is, the information for identifying a disc information type can identify the corresponding disc information is in CLV mode or CAV mode. 例如,如上所述,把各种可以存在的写入策略类型,比如(n-1)WS、n/2 WS等,定义为第1个WS WS-1、第2个WS WS-2以及第K个WS WS-K。 For example, as described above, various write strategy type to be present, such as (n-1) WS, n / 2 WS, etc., is defined as a first WS WS-1, 2nd WS WS-2, and the second the K WS WS-K. 把盘片制造商选择的用于识别写入策略类型(被称为'WS类型')的信息记录在盘片信息内。 The disc manufacturer information for identifying the selected write strategy type (referred to as 'the WS Type') is recorded within disc information.

图9B是根据图9A中本发明第四实施例将写入策略记录到控制信息内的图,图9C是根据图9A中本发明第四实施例将写入策略记录到控制信息内的另一个实例的图。 9B is recorded in the write strategy within control information according to FIG fourth embodiment of the present invention, FIG. 9A, FIG. 9C is a recorded write strategy within control information according to another embodiment of the fourth embodiment of the present invention in FIG. 9A example of FIG.

图9B示出了在记录多个写入策略(WS)之一的过程中盘片制造商任选性地针对全部写入速度记录特定写入策略(WS)。 FIG 9B illustrates a process of one write strategy (WS) recorded in the plurality of disc manufacturer optionally records a specific write strategy (WS) for entire writing speeds.

参照图9B,盘片信息的第N个字节表示盘片信息类型,盘片信息的第P个字节表示写入策略(WS)类型,并且在第L到第11个字节中记录一些参数,这些参数与通过与第N个和第P个字节相互作用而确定的一种写入策略(WS)相关联。 9B, the N-th byte of disc information indicates a first P type byte disc information, disc information indicates a write strategy (WS) type, and some of the records to L 11 bytes parameters, with one determined by the interaction with the N th and P th bytes strategy (WS) associated with the writing.

例如,在'00h'中记录用于第一记录层的1倍速的盘片信息作为盘片信息顺序,盘片信息类型意味着CAV模式,写入策略(WS)类型意味着第一WSWS-1,并且写入策略(WS)与它们相互作用,所以选择记录CAV WS-1。 For example, in '00h' in recording disc information for lx speed of a first recording layer as a disc information sequence, a disc information type means CAV mode, a write strategy (WS) type means a first WSWS-1 , and write strategy (WS) and their interaction, the selected recording CAV WS-1. 在'01h'中记录用于第一记录层的2倍速的盘片信息,盘片信息类型意味着CLV模式,写入策略(WS)类型意味着第一WS WS-1,并且写入策略(WS)与它们相互作用,所以选择记录CLV WS-1。 In '01h' of 2 × speed recording disc information for a first recording layer, a disc information type means CLV mode, a write strategy (WS) type means a first WS WS-1, and a write strategy ( WS) interact with them, so the choice of recording CLV WS-1. 在'02h'中记录用于第一记录层的4倍速盘片信息,盘片信息类型意味着CLV模式,写入策略(WS)类型意味着第2 WS WS-2,并且写入策略(WS)与它们相互作用,所以选择记录CLV WS-2。 In '02h' for the 4-times speed recording of the first information recording layer disc, disc information type means CLV mode, a write strategy (WS) type means of 2 WS WS-2, and a write strategy (WS ) interact with them, so the choice of recording CLV WS-2. 在'03h'中记录用于第1记录层的8倍速盘片信息,盘片信息类型意味着CAV模式,写入策略(WS)类型意味着第2种WS WS-2,并且写入策略(WS)与它们相互作用,所以选择记录CAV WS-2。 8x disc information '03h' is recorded for the first recording layer, the type of disc information means CAV mode, a write strategy (WS) type means that the second type WS WS-2, and a write strategy ( WS) interact with them, so the choice of recording CAV WS-2.

图9C示出了在盘片信息之内记录多个写入策略(WS)之一,其中针对特定的指定写入速度(例如,1倍速)来记录强制性的写入策略(WS)类型,但盘片制造商任选地记录用于其余写入速度的特定写入策略(WS)。 9C shows a recorded write strategy in the disc information of one (WS), in which to record the mandatory write strategy (WS) type for a specific specified writing speed (e.g., speed 1), but a disc manufacturer optionally records a specific writing speed for the rest of write strategy (WS).

由此,图9C中的方法与图9B中的方法的不同之处在于,针对特定的写入速度(1倍速),通过对盘片制造商的选择加以限制,便可以以强制的方式来确定写入策略(WS)类型。 Thus, the method of FIG. 9C differs from the method in FIG. 9B in that, for a specific writing speed (speed 1), be limited by the choice of the manufacturer of the disc, can be determined in a mandatory manner write strategy (WS) type. 这使盘片记录/再现装置(图10)的制造商能够设计制造并不昂贵的产品,用于仅处理一种写入策略(WS)。 This allows the disc recording / reproducing device manufacturer (FIG. 10) can be designed for producing inexpensive product for only handle one write strategy (WS).

例如,在'00h'中记录用于第1记录层的1倍速的盘片信息作为盘片信息顺序,盘片信息类型意味着CAV模式,写入策略(WS)类型意味着第一WSWS-1,并且写入策略(WS)与它们相互作用,所以以强制的方式选择CAV WS-1并记录。 For example, in '00h' in recording disc information for lx speed of a first recording layer as a disc information sequence, a disc information type means CAV mode, a write strategy (WS) type means a first WSWS-1 , and write strategy (WS) and their interaction, forced manner so selected CAV WS-1 and recorded. 在'01h'中记录用于第一记录层的2倍速的盘片信息,盘片信息类型意味着CLV模式,写入策略(WS)类型意味着第1种WS WS-1,并且写入策略(WS)与它们相互作用,所以选择CLV WS-2并记录。 2x speed disc information '01h' for the first recording layer is recorded, and disc information type means CLV mode, a write strategy (WS) type means that the first type WS WS-1, and write strategy (WS) and their interaction, the selection CLV WS-2, and recorded. 在'02h'中记录用于第一记录层的4倍速的盘片信息,盘片信息类型意味着CLV模式,写入策略(WS)类型意味着第2种WS WS-2,并且写入策略(WS)与它们相互作用,所以选择CLV WS-2并记录。 In '02h' in recording disc information for 4x speed of the first recording layer, disc information type means CLV mode, a write strategy (WS) type means that the second type WS WS-2, and a write strategy (WS) and their interaction, the selection CLV WS-2, and recorded. 在'03h'中记录用于第一记录层的8倍速的盘片信息,盘片信息类型意味着CAV模式,写入策略(WS)类型意味着第2种WS WS-2,并且写入策略(WS)与它们相互作用,所以选择CAV WS-2并记录。 8x disc information '03h' in the first recording layer for recording, the type of disc information means CAV mode, a write strategy (WS) type means that the second type WS WS-2, and a write strategy (WS) and their interaction, the selection CAV WS-2, and recorded.

图9D示出了根据本发明第四实施例记录控制信息的另一个实例,其中细分用于CAV模式的特定标识,以应用于在盘片信息内第N个字节中所写入的“DI类型”字段,并且其中也记录了用于指定写入策略(WS)类型的信息。 FIG 9D shows another example of recording control information to a fourth embodiment of the present invention, in which specific identification for CAV mode is subdivided to be applied to the N-th byte within disc information writes " DI type 'field, and which also records information for specifying a write strategy (WS) type.

参照图9D,当相应的盘片信息意味着CAV模式时,将其细分以识别写入策略(WS)提供了多少种速度。 Referring to Figure 9D, when the corresponding disc information means CAV mode, subdivided to identify a write strategy (WS) provides many speeds. 因此,“DI类型”字段可按下文来定义。 Thus, "DI Type 'field can be defined hereinafter. 如果在第N个字节中所记录的“DI类型”字段是'0000 0001b',则它意味着CAV模式,并且记录在第L到第111个字节中所记录的写入策略(WS)以对应于仅一种速度。 If the N-th byte recorded "DI Type 'field is' 0000 0001b', it means CAV mode and recorded at the first write strategy L to 111 bytes recorded (WS) corresponding to only one speed. 如果在第N个字节中所记录的“DI类型”字段是“0000 0010b”,则它意味着CAV模式,并且记录在第L到第111个字节中所记录的写入策略(WS)以对应于两种速度。 If the N-th byte recorded "DI Type 'field is" 0000 0010b ", it means CAV mode and recorded at the first write strategy L to 111 bytes recorded (WS) corresponding to two speeds. 如果在第N个字节中所记录的“DI类型”字段是'00000011b',则它意味着CAV模式,并且记录在第L到第111个字节中所记录的写入策略(WS)以对应于三种速度。 If the N-th byte recorded "DI Type 'field is' 00000011b', it means CAV mode and a write strategy recorded in the L th byte to the 111th recorded (WS) to corresponding to the three speeds.

此外,把'写入策略(WS)类型'字段添加到盘片信息内第P个字节,所以通过与第N个字节中的盘片信息类型和第P个字节中的写入策略(WS)类型相互作用,来记录第L到第111个写入策略(WS)。 Further, to add the 'write strategy (WS) Type' field of P into the disc information bytes, by disc write strategy type information in N th byte and the second byte in the P (WS) type interaction to records of 111 L to the write strategy (WS). 即,它可以定义如下。 That is, it can be defined as follows. 如果在第P个字节中写入'0000 0000b',则它意味着第一个WS WS-1。 If written in P th byte '0000 0000b', it means that the first WS WS-1. 如果在第P个字节中写入'0000 0010b',则它意味着第2个WS WS-2。 If written in P th byte '0000 0010b', it means 2nd WS WS-2. 如果在第P个字节中写入'XXXX XXXXb',则它意味着第K个WS WS-K。 If written in P th byte 'XXXX XXXXb', it means K th WS WS-K.

图9E是可与图9D相比的将写入策略记录到控制信息之内的图。 FIG. 9E FIG 9D is recorded into the write strategy within control information of FIG compared.

参照图9E,在第N个字节的'DI类型'字段中写入'0000 0000b'以便意味着CLV模式。 Referring to FIG. 9E, is written in the N th byte is 'the DI Type' field, '0000 0000b' to mean CLV mode. 在第P个字节的'写入策略(WS)类型'字段中写入'00000000b'以便意味着第1WS WS-1。 Write "00000000B" to mean 1WS WS-1 of the first byte P 'write strategy (WS) Type' field. 第5个字节是'00h',用来表示第一记录层的1倍速盘片信息。 5th byte is '00h', disc information for 1x represents the first recording layer. 并且,在盘片内第L到第111个字节中写入与第N和第P个字节相互作用的特定的写入策略(WS)。 And, writing a specific write strategy (WS) to interact with the N-th and P th bytes within the disc 111 to the L th byte.

因为是CLV模式,所以记录了用于一种速度的写入策略(WS)。 Because a CLV mode, a write strategy for recording of one speed (WS). 当它是第1种WS WS-1时,例如,可定义'(n-1)WS'类型的参数。 When it is the first type of the WS 1 WS-time, for example, define '(n-1) WS' type parameter. 因此,盘片制造商将最佳值记录到相应盘片中。 Accordingly, a disc manufacturer records an optimal value in a corresponding disc.

如果把'DI类型'字段(第N个字节)设置成'0000 0001b'以表示CAV模式,或如果把'写入策略(WS)类型'字段设置成'0000 0010b'以表示第2种WS WS-2,则很明显,应该记录写在第L到第111字节中的写入策略(WS)参数作为不同于图9E所指定的参数或相应参数的值的新内容。 If 'the DI Type' field (N th byte) is set to '0000 0001b' to represent CAV mode, or if 'Write Strategy (WS) Type' field is set to '0000 0010b' to indicate the second type WS WS-2, it is clear that, (WS) as the parameter values ​​are different from 9E specified parameter or parameters corresponding to FIG record new content to be written in the L to 111 bytes of write strategy.
